In your WF - do you have any custom steps. Show a pic of the model and where this exception occurs.

In response to smacdonald2008

smacdonald2008​

Thanks for the help here.

Attached is the screenshot of workflow, this exception occurs at starting of the workflow.

Means first step which dynamically assigns approver group based on country where user is activating content.

  public String getParticipant(WorkItem workItem, WorkflowSession wfSession, MetaDataMap metaDataMap)

    throws WorkflowException

  {

    LOGGER.info("####### Participant : " + this.CONTENT_APPROVAL_GROUP + " ##############");

    Session jcrSession = (Session)wfSession.adaptTo(Session.class);

    ResourceResolver resourceResolver = getResourceResolver(jcrSession);

    WorkflowData workflowData = workItem.getWorkflowData();

    String payLoadPath = (String)workflowData.getPayload();

    String contentApprovalGroupID = "";

    try

    {

      contentApprovalGroupID = DialogUtil.getcountryWiseGroupIdentity(payLoadPath, resourceResolver, "contentmanagergroup");

      if ((null != contentApprovalGroupID) && (!"".equals(contentApprovalGroupID)))

      {

        String[] contentApprovalGroupEmail = DialogUtil.getApprovalGroupEmail(resourceResolver, contentApprovalGroupID);

        if ((null != contentApprovalGroupEmail) && (0 < contentApprovalGroupEmail.length)) {

          this.dialogEmailService.sendEmailNotification(this.EMAIL_TEMPLATE_PATH, workItem, contentApprovalGroupEmail);

        }

      }

    }

    catch (RepositoryException e)

    {

      LOGGER.error("Exception in DialogParticipantStepChooserImpl", e);

    }workflow.png

    return contentApprovalGroupID;

  }

Workflow doesn't have any issue as the same workflow is working in another environment.

After modifying Adobe Granite workflow service in configMgr we are facing this issue only in this specific environment
